As to the age of the video, based on my common sense, novice forensics, I woud guess it was made sometime within the last 5 years.
1. The pixel quality of the video seems very good with little or no artifacts associated with aged video that's on tape. This means its not on video tape (and was not taken in the 1980's).
2. The shakiness of the camera operator suggests that the camera was a hand-held device like an iPad, iPhone or some other phone/tablet camera. Such devices have only recently - within the last 5 years - become very ubiquitous.
3. The clothing seems very modern - late 1990s or later.
4. Looking at Jackson's physical appearance, there is little or no difference between his age in the video and his age in very recent photos and videos. (He does not look perceptibly younger)
All of this leads me to the conclusion that the video was made very recently, sometime within the last 5 years.
